| Abstract: | A study on the change of abscisic acid and indole-3-acetic acid in pear fruitlets during growing periods is important for the research on the pollination and fertilization of pear. Abscisic acid and indole-3-acetic acid were converted into pentafluorobenzyl esters by a-bromo-2,3,4,5,6-pentafluorotoluene.The two generated esters were able to be simultaneously determined with electron-capture gas chromatography without other processes. The recovery of abscisic acid and indole-3-acetic acid were 95.8% and 84.5% respectively. The method was simple, sensitive and reliable. |
| Keywords: | Pear fruitlets Abscisic acid Indole-3-acetic acid Electron-capture gas chromatography |
